What is THE BEST Antivirus program? Why? My McAfee provided by AT&T (DSL internet browser) is pissing me off. It has stopped working. Every time I do a virus scan the computer shuts down half way through. And the built in spam and pop up blockers have always sucked! Besides, I am about to switch internet providers to Sprint. I already use them for wireless. I had PC Cillin before, it worked too good, blocked EVERYTHING. Couldn't look at a lot of websites, use paypal, etc... so F that! I tried the free AVG before, it is garbage. It let a lot of viruses through. My last computer was infected so bad using it, I decided to just get a new one. So any recommendations? Heard any good reviews?
